        Acne, pimples, and breakouts are collectively known medically as acne, and are a common chronic condition of the sebaceous glands. The cause is that during puberty, hormones in the body stimulate hair growth and sebaceous glands secrete a lot, resulting in clogged pores forming a core of acne – microcomedones. Microcomedones are invisible, and it takes 7 to 9 months for a microcomedone to form and grow out of the skin’s surface. Microcomedones clog pores and induce inflammation, which is the origin of pimples, pustules, nodules and cysts. Conventional treatment only removes the surface acne, and the microcomedema grows back after a period of time, resulting in recurring acne flare-ups.
